Abstract
A plurality of modules housed in a chassis is secured to the railroad tie to capture high resolution images of the underside of a train car as it passes over the plurality of cameras. These images are important to insure the structural integrity of the parts of the rail car as well as the connection means—a coupler and pin—between two rail cars. The cameras are configured to capture at a predetermined rate or to operate in sync with the velocity of the train as measured by the Linear Speed Sensor. As the images are taken, the images can be downloaded and sent to a remote location for further analysis.
Description
- The applicants are filing this continuation in part and are claiming priority from the previously filed application that was filed on May 21, 2021 with the associated Ser. No. 17,326,427.
- Trains crisscross the county and are used to transport goods. Trains are comprised of multiple cars and travel on designated routes over tracks. The cars are joined together using couplers; there are many types of couplers in use for this means of transport. It is important for the safe transport of trains that the cars remain coupled. If there is a failure of the coupler and the train cars separate, the train could derail and cause serious personal injury or property damage.
- It is important to evaluate the integrity of the coupler system while the train is moving and other components of the train car. The current application positions a plurality of cameras on the tracks; these cameras will take high speed images of the underside of the train car. The placement of the cameras will focus on taking high resolution images of the coupler system between the train cars on the train and other structural components of the underside of each individual freight car.
- Freight Trains consist of individual freight cars interconnected by a coupler system. All coupler systems use a pin to connect the coupler to the car. These pins utilize various retainment methods to ensure the continuous operation of the coupler system. Failure of this coupler system, specifically the pin and or pin retainment method will result in train separation and worst-case a derailment.
- While there are many types of couplers in use, a specific coupler type known as the F type, positions this pin on the underside of the car. There is a retainer system that resembles the letter “F” which captures the Pin with the addition of a cotter pins and Pin securement device.
- In order to inspect the F-pin, as required by the Federal Railroad Administration at periodic intervals, the train would be stationary and an individual would manually inspect each pin and retainment device by positioning themselves under the train to view the device. This application allows images of the car undercarriage components, including the coupler system, to be taken while the train travels at full speed. Images are stored for a period to allow for an intelligence, human or artificial, to evaluate for any defects.
- There is prior art that uses multiple cameras to take images from multiple views and a representative example can be found at Buibas, U.S. Pat. No. 10,282,852. This reference is used to track an individual in a store and multiple cameras are placed in the store to track the individual. While this application also uses multiple cameras, the cameras in this application are designed to take high speed images of the undersigned of a rapidly moving objects i.e. moving train cars.
- Another example of the prior art can be found at Schofield, US Patent Publication 2017/0237946 which is a cabin monitoring system. This application tracks the movement of an occupant inside a vehicle. While multiple cameras are used in this instance, this application does not employ a plurality of lights that are activated at certain predetermined times.
- Another example in the prior art that monitors the condition of train tracks using sensors can be found at Singh, U.S. Pat. No. 10,518,791. This device is not designed to take images of the underside of a moving train.
- While there are other prior art references, none of the references teach the multiple features that are found in this application.
- This application positions cameras and illumination elements known as modules in a predetermined fashion and at predetermined angles. The modules are engineered to support a range of environmental conditions as well as manage internal thermal requirements from the illumination elements. The system is designed to operate during precipitation events though conditions may impact image quality. The system is recommended to operate under a canopy to reduce the impacts of precipitation and solar illumination interference.
- In the railroad industry it is imperative that the structural integrity of the underside of the freight train is maintained. While the device captures images of the integrity of hoses and other connections, it is especially important to capture the images of the F-pin and its securement means.
- Railroad cars are coupled together using a coupler; a coupler is used between each railroad car. On one end of the coupler is a knuckle assembly that extends from the train and mates with a corresponding knuckle coupler on the car adjacent to the train car. On the opposite end from the knuckle of the coupler is an opening on the truck assembly; the F-pin is inserted into this opening and is secured to the underside of the train car. A retainment mechanism is placed near the opening for the F-pin to ensure that the F-pin remains in place during normal operation of the train. If the F-pin fails or is dislodged, the train cars will decouple.
- During normal operation of the train the F-pin and its retainment mechanism is hidden from view by other components of the train. It is, however, visible from the side of the underside of the train. The cameras are placed to provide a mechanism to capture the images of the F-pin by positioning the cameras to capture the views of the F-Pin.
- All the modules are equipped with LED light that surround the lens. There are six LED lights, and they were placed as close to the camera lens to eliminate shadowing. The LEDs however produce a great amount of heat and that was one of the considerations when the placement of the LED was being considered.
- There is a total of eight modules arranged on two chassis of the same design. The two chassis are arranged to face each other and each mount to a single rail tie. Each of the Chassis are protected by a skid plate and deflector at the rear.
- There are four modules on each chassis. Each module is arranged upward at a predetermined angle relative to the top of rail. The four modules are positioned in the same plane adjacent to each other but are angled such as the inner cameras are arranged outward at a predetermined angle relative to the track centerline and the outer cameras are arranged inward at a predetermined angle relative to the track centerline.
- The system is operated by a software control system to activate the illumination and activate the capture of images by the cameras. The current application employs technology that is in use to determine the speed of a moving train. The system can be configured to capture images proportionally with the speed of the train or operate in a condition known as “Free Run” where a pre-determined capture rate is established.
- The position of the two chassis, established orientation of the modules within the chassis, and the configuration of LEDS with respect to the camera lens are specific to capture images of the F-Pin and F-pin retainment devices. In addition, this configuration provides the ability to capture images of various undercarriage components of a passing freight car.
